View 11 - Lots of sensors and polarizer pieces. These units run the arc
lamp at 100% rated power all the time and they vary the output power with a
circular polarized disk which varies the polarization and thus
attenuates output power Note the purple glow on the optics holders the
camera picked up however your eye's would not until it's way to late...
(Huge IR power is way dangerous from an eyesight standpoint.)

View 18 - That's one bright beam even with all the lights on and look at
the scattered of the beam stop in the next room at distance it almost lights
up the other room's 7,500 square foot area.

View 19 - Far from a 100 micron clean room dust is ever present and very
visible when illuminated with this much power.

View 20 - Another top view of part of the cavity and optics tray. The
YAG and arc-lamp are under the cover with the High Voltage warning sign.

View 21 - Most of the optics tray.
Lower left is the output coupler for the 532 nm (VIS) and HR
for the 1064 nm (IR) of the Z-fold resonator and square black box is the
RF Q-switch (10 kHz). Upper right is the KTP oven and holder assembly optic
just above the Q-switch is the HR for both 1064 and 532 nm. Another HR
1064/532 nm for the cavity-end is just the other side of the cavity.
